One of the great things about movies is that there really is something for everyone.
If you want to shut your brain off and watch things explode for two hours, you can do just that. If you need cheering up and want a good laugh, you have hundreds of solid options to choose from. If you want to be challenged, inspired, or even scared, there are more than enough flicks available to feed those desires.
Studios also have a lot of options when it comes to the films they choose to greenlight, only, from their point of view, they're mainly thinking about commercial viability. Some movies are safe bets that are almost guaranteed to earn a positive reception, while others are more risky, projects that studios can be hesitant to send out into the world, or - in some extreme cases - be reluctant to make in the first place.
Maybe it's a movie with some controversial subject matter, an unproven lead actor, or, y'know, maybe the studio just hates the damn thing. Even faceless corporations feel fear sometimes, and these movies incited some genuine concerns on behalf of the studios who were putting up the cash to make them.
